It used to be that beefy 908 '70-'72 Six Pack rods (foreground) were the hot ticket. After all, bigger is better, right? Not when they add 100 grams of reciprocating mass each. While original Max Wedge 886 rods offer the best OE strength-to-mass compromise and there are plenty of aftermarket upgrades available, the stock forged-steel 535 rods are safe up to 600 hp in a stock-stroke budget setting like this. At a weight of 830.8 grams (versus the Six Pack's 930.8 grams) Superior Magnafluxed each rod, fitted high-strength ARP fasteners, then resized them. Beam polishing was deemed unnecessary for this fairly mild, 6,500-rpm application.
